Charles Hoskinson, co-creator of Ethereum and creator of Cardano, a peer-to-peer blockchain that supports smart contracts and the cryptocurrency Ada, says Google’s recent claim about a quantum breakthrough is a watershed moment like Sputnik, the first artificial Earth satellite ever, launched by the Soviet Union on October 4, 1957.
While crypto supporters continue to weigh revelations about Google’s advancements in the field of quantum computing, wondering when and if the day will arrive when a supercomputer can crack Bitcoin’s cryptographically-secured blockchain technology, Hoskinson draws a line between the theoretical and the practical.
In an ask-me-anything session on Saturday, Hoskinson responded to a question about whether or not he believes that Google has reached quantum supremacy. He replied,
“According to their definition: yes. Unfortunately, there is a huge delta between what they’ve done and what’s required to actually use quantum computers to become problematic for cryptography. But it is a major milestone. It’s an example of the endless and relentless progress that companies can make once they’ve set their mind to something, and they have the people to execute.
The reality is this computational model is here to stay. The physics are sound and it’s more of an engineering problem than a theoretical problem at this point. There’s certainly a lot of science to do and a lot of math to do and a lot of careful programming to do, but today it feels more inevitable than it did 10 years ago about whether a quantum computer will ever exist and be useful and solve real problems. And kudos to Google’s team out of Santa Barbara for the amazing work that they did there. This is literally the rocket science of our time. It’s probably the most difficult engineering mankind has ever embarked upon.
